BRICK-MACHINE WITH SANDER ATTACHMENT.

SPECIFICATION forming part of Letters Patent N 0. 654,846, dated July 31, 1900.

Application filed April 21, 1900..

T0 at whom it may concern:

Be it known that LHERBERT SOHOONMAKER, a citizen of the United States,whose residence and post-office address is Roseton, county of Orange, State of New York, have invented con tain new and useful Improvements in Brick- Machines wit-h Sander Attachments, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. p

The object of the present invention is to combine a brick-machine with a brick-mold sander arranged and operated to sand the molds, to jar the surplus sand from the same in an inverted position, and to deliver the sanded molds at suitable intervals in an upright position upon the table of the machine.

The brick-mold sander shown herein is specifically claimed by me in a separate application but it is immaterial to the present invention what construction of apparatus is used to sand the molds, provided it is com bined with the brick-machine so as to deliver the sanded molds at suitable intervalsin an upright position upon the brick-machine table. In the present invention I extend a pla t form from the table of the brick-machine, upon which table the molds are filled with clay, and arrange the sanding-machine to deliver the molds upon such platform, and I provide means for sliding the sanded molds at regular intervals from the platform to the table of the brick-machine. To slide the sanded molds at proper intervals to the brick-' machine to cooperate with the press for the brick-mold, I connect the shifting devices with the crank-shaft of the brick-machine, and I also connect the brick-mold sander with the same crank-shaft, so that the molds may. be sanded and delivered to the platform at the same rate at which" they are'filled and pressed in the machine.

The invention will be understood by reference to the annexed drawings, in which Figure 1 is an end view of the sanding-machine with the brick-machine at the farther end of the same, only those parts of the brickmachine being shown which are necessary to connect with the sanding-machine. Fig. 2 is a side view of the sanding-machine, showing, the platform in section and the devices for.

sliding the molds from the-same to the table Serial No. 13,715. (No model.)

E is a platform extended fromthe level of the table sufficiently to receive the upright molds from the sanding-machine, which is shown constructed with a sanding-cylinder ct, having a shaft a, geared to the crank-shaft B. The shaft a carries heads I), having seats b and lugs c to receive and propel the molds within the sanding=cylinder. The sanding cylinder has an opening near the top to reeeive the molds and a guide f to hold the molds in'contact with the heads which carry them successively into the cylinder by their rotation. Each of the seats is in practice provided with a'blade which lifts the sand from the bottomof the cylinder and spills it intothe mold, as is common in such machines. A reversing-cylinder d is fixed over an opening on the top of the sanding-cylinder, and the molds are transferred into the bottom of such cylinder from the heads I) by ways 0. The cylinder d is provided with shaft d, having disks h with lugs h to grasp the molds and deliver them to theplatform E. The molds are inverted in their passage through the reversingcylin'der, so as to stand in an erect position when discharged upon the platform, and are removed from the disks by strippers k,which' incline downward to the table, so that the molds slide outside of the reversing-cylinder when discharged. The shafts of the sanding cylinder and reversing-cylinder are connected by gears or cog-wheels m, and one of such gears is driven from the crank-shaft B by sprocket-wheels n and s procket-chain P. The disks h deliver two molds to the platform E at each rotation and are turned by the gearing one revolution when the crank-shaft B is rotated twice, and one mold is thus delivered to the platform for each rotation of the crank shaft.

The devices shown for transferring the molds successively from the platform to the brick-machine table consist of two levers G and H, pivoted and connected to the crankshaft B in such manner as to vibrate in opposite directions and each operating upon the same mold successively to move it by two impulses into the proper position upon the table. The lever H is pivoted upon a bracket J, near the top of the brick-machine, and is provided with a bell-crank arm H, projecting toward the machine. A lever L is pivoted upon the side of the brick-machine and extended past the arm H to the end of the crank-shaft, where it is provided with a slot M to engage the pin of a crank N, secured upon such shaft. The arm H is fitted to a socket in the lever L, and the leverH is thus vibrated upon its fulcrum J by the rotation of such crank-pin. The lever G is pivoted intermediate to its ends upon a pin P upon a bracket below the bracket J, and its upper end is connected with the lever H below its fulcrum J by adjustable link Q. The levers G and H are thus moved simultaneously in reverse directions. The lever G is provided, near its lower end, with a laterally-projecting shoe G, and the lever H vibrates at one side of the lever G and carries a pawl I central over the shoe, so that both shoe and pawl are enabled to press upon the center portion of the mold and push it squarely forward to the table. The pawl is provided with a lug or toe I at its forward upper corner to rest upon the mold and prevent the pawl from slipping off of the same in its backward movement. The operating ends of the levers being at different distances from their fulcra, the lever H is traversed through a greater space than the lever G but the parts are so proportioned that the lever G shifts the mold from its first position 0 upon the platform to the position 0 in which the pawl may readily engage its rear end.

The slot M is curved at its outer end concentrically with the movement of the crankpin, so as to hold the lever H stationary for a suitable period when the pawl I is in its outer position, as shown in Fig. 2, thus giving the pawl time to drop positively upon the rear side of the mold. The slot is thereafter curved in the opposite direction, which produces a quick return motion of the lever H. 'The pawl is made of sufficient length to force the mold into the aperture E, which is formed in the side of the brick-machine above the table E and is thus enabled to place the mold centrally upon the table, where the pusher D may shift it to the press.

The ordinary mechanism for operating the pusher is shown in Figs. 1 and 2, consisting of levers S and T, connected by link S and lover U, operated by dog V upon the wheel V. This wheel is attached to the crankshaft, and thus actuates the pusher once at each movement of the brick-press to place a mold beneath the same.

The table of the brick-machine is shown in Fig. 1 extended from the front of the machine to support the molds as they are dis charged successively from the press, one of the molds 0 being shown upon such table.

From the above description it will be seen that the sanded molds are delivered upon a table of the brick-machine in asuitable position to be filled and pressed in the usual manner, by which the labor of one operator isentirely dispensed with, as it is necessary even if a brick-mold sander be used in the ordinary manner for an operator to take the molds from such sander, dislodge the surplus sand, and place the molds in a suitable position upon the brick-machine table.

' The apparatus is simple and cheaply con structed, and the adjustable connection between the levers G and H permits them to be set in an operative relation to one another when the machine is constructed. The molds must unavoidably be moved a considerable distance to transfer them from the sandingmachine to the brick-machine, and if a single lever were used for such purpose it would move through so large an arc as to rise inconveniently above the platform at the ends of its stroke. By using the two levers G and H the are through which each vibrates is materially reduced and the mold is shifted with less strain upon the parts.

Having thus set forth the nature of theinvention, what is claimed herein is 1. The combination, with a brick-machine having a table'to receive the molds and sustain the same during the filling operation and having a crank-shaft to operate its press, of a platform extended from such table, a sanding-machine with devices for delivering the sanded molds upon such platform, and means for sliding the sanded molds from such plat form to the table of the brick-machine, substantially as herein set forth.
